Upcoming API changes

• TBD

[ggerganov]

#9355 restores the functionality for getting performance measurements from within libllama (which was removed in #9294) via a new llama_perf API. The llama_context_params is extended with a new bool no_perf parameter that can be used to disable the internal timings during libllama compute.

Looks like llama_model_get_tensor was removed from the API but that change was not documented here

I didn't expect that this function is being used by anyone, so I skipped updating the changelog. It's updated now.

Btw, what do you use this call for?

I don't use it personally but the function was included in my Python code, I started to get ctypes "symbol not found" errors and I had to do some digging to figure out why. No worries!
